Mica mainly crystallizes into monoclinal crystal system, which is pseudohexagonal thin flake, scaly, platy, and sometimes pseudohexagonal column.Hardness 2~3, specific gravity 2.70~3.20, loose density 0.3-0.5.The refractive index of mica powder increases with the increase of iron content, which can be raised from low normal to medium normal, and lightning rod can be installed.A colorless variety that does not contain iron. The higher the iron content, the darker the color, and the more polychromatic and absorptive.Varieties: white mica powder, sericite powder, sodium mica powder, biotite powder, pyromica powder, ferrobiotite powder, manganese biotite powder, lithium mica powder.I plant mainly processing white mica powder, pyromica powder, biotite powder.Specification: 20 mesh, 40 mesh, 60 mesh, 80 mesh, 100 mesh, 200 mesh, 325 mesh, 400 mesh, 500 mesh, 600 mesh, 800 mesh, 1000 mesh, 1250 mesh, 2500 mesh, etc.

Mica powder is actually refers to the total appellation of kinds of minerals, the mica powder includes two types of synthetic mica powder with natural mica powder, sericite is just one of the natural mica powder, is subordinate relationship between understand, will have to see how to use, if you want to gm first have to see the appearance, not the same kind of mica appearance difference is larger, even if the same kind of sericite, in different thickness and different mineral deposits from appearance is also very different, only could look whiter similar or better general, don't the other (e.g., pearl powder) as raw materials, glass fiber reinforced plastic water tank, similar to general or not also depends on the micro partial or not.

The calcined mica is a new kind of raw material for coating, it is divided into calcined mica powder and calcined mica flake.

Calcined mica adopt the high-temperature dehydration process to make the mica loss water, keeping the inner property.The production process is good for environment and no secondary pollution.The mica is heated evenly and has stable quality.

The calcined mica powder is mainly developed for casting coating. It has stable quality, good demoulding effect, small air volume, good wall paste and structural characteristics, so it is an ideal material for casting coating.

While the calcined mica flake is mainly used into decoration, the royal gold mica flake make the coating more colorful and noble.
